[Illustration: CHAMBERS’S JOURNAL OF POPULAR LITERATURE, SCIENCE, AND ART Fifth Series ESTABLISHED BY WILLIAM AND ROBERT CHAMBERS, 1832 CONDUCTED BY R. CHAMBERS (SECUNDUS) NO. 22.—VOL. I. SATURDAY, MAY 31, 1884. PRICE 1½_d._] OUR DETECTIVE POLICE. The number of murders that have taken place, and the very few murderers that have been brought to justice in and about London during the last few months, must go far towards contradicting the assertion to the effect that the metropolis of England is ‘the safest city in the world’ to live in. And if to the list of crimes against life which have not been, and never are likely to be, brought home to the perpetrators, we add the innumerable thefts, burglaries, and other offences against property which go unpunished because the criminals are never found out, it can hardly be denied that we require a new departure in the system of our Detective Police, for the simple reason that, as at present constituted, the practical results of the same are very much the reverse of satisfactory. It has been my lot, for reasons which need not be entered into here, to see not a little of the French detective system, and of the plans adopted by those employed in discovering crime in Paris. The two systems, those of the London and Parisian detective, differ most essentially. With us, it is as if the general commanding an army in the field was to send spies into the enemy’s camp, taking care they were dressed and behaved themselves in such a manner that every one would know who they were. On the other hand, the French system of detection is based on the principle that the enemy—namely, the criminals amongst whom they have to make their inquiries—should never be able to discover who the spies are. Now, with some fifty or sixty detectives trained to perfection in the art of disguising themselves, must it not be far more easy to discover the whereabouts of crime and the identity of the criminals, than can possibly be done under our system? Our detectives are as well known to a Londoner of any experience, and we may presume they are also just as well known to the criminal classes, as if they wore uniform. Nay, in a very useful volume called _The Police Code and Manual of the Criminal Law_, compiled by Mr Howard Vincent, it is clearly laid down that ‘the idea that a detective to be useful in a district must be unknown is erroneous in the great mass of cases, as he is then unable to distinguish between honest men who would help a known officer and others.’
